System Security Guide
- Cell Level
The electric core adopts LFP material system, wich has extremely high safety. In addition, one-way explosion-proof walve is designed on the top. In case of emergency, such as short-time connection outside, the explosion-proof valve can be punched open to cut off the circuit to prevent large safety risks.
- Module Level
The temperature control module controlled by BMU at the module level can adjust the temperature in the module in real time to ensure that the operating environment is in a controllable range.
- Rack Level
Rack level is mainly through the CBMS internal DC circuit breaker, reply, pre-charge resistance and diode and other power devices, the system to achieve overcharge, over-current, anti-reverse connection and other state management, to ensure the safety and reliability of the rack.
- System Level
The main purpose of the system is to control the pressure difference between racks in the parallel machine state, and realize the balance adjustment between racks through pre-charge resistance to ensure the safety of system operation.
Battery Monitor System Guide
- 1. According to the battery modules connected in series after the total voltage is divided into three grades
U-BMS-LV, 10 ~ 64V (series 4 ~ 16 cells).
U-BMS-MV, 10 ~ 96V (series 4 ~ 24 cells).
U-BMS-HV, 96 ~ 300V (series 4 ~ 80 cells).
- 2. Interface
The one RS-485 for battery module;
The other RS-232 with PC or other controller connection;
The 5 signals "0" or "1" output signal; GPIO1 ~ GPIO5.
The 2 signals universal input or output port; GPIO6 ~ GPIO7 (standby).
- 3. BMS power supply
U-BMS-LV and U-BMS-MV from the string of battery power or the external DC12V power supply; U-BMS-HV built-in 10AH3.6V rechargeable battery, battery charger charging.
- 4. The power consumption of BMS
U-BMS-LV and U-BMS-MV: 0.3W ~ 0.8W
U-BMS-HV: 0.4W ~ 0.6W
- 5. BMS working mode
Master mode: the whole battery modules`system managed by BMS, RS-232 for monitoring;
Slave mode: PC may control BMS to manag battery system used RS-232 to recieve data and send command.
- 6. The BMS function
Battery configuration, such as Series or parallel;
Battery module address management;
Battery system state judgment: charging, discharging, static;
RS-485, RS-232 Bus management;
According to data, control protection switches.
